Cryogen Reclamation System

Cryogen Reclamation System

JEOL’s new Cryogen Reclamation System offers a convenient, reliable and highly effective solution to managing and maintaining your NMR instrument’s cryogen levels by substantially reducing the evaporation of liquid helium and liquid nitrogen from the superconducting magnet (SCM) via helium and nitrogen recovery.

Key Features

  • Substantially reduces the evaporation of liquid helium and liquid nitrogen from the superconducting magnet (SCM)
  • Significantly reduces the frequency and costs of cryogen refills
  • Maximizes NMR instrument uptime, reduces the risk of shutdown due to cryogen supply issues
  • Lightweight, space-saving design
  • Low vibration of the System ensures excellent data quality and low artefact levels
  • Can be retrofitted to existing JEOL NMR instruments with the SCM maintained “at field”

With the Cryogen Reclamation System, there is almost no change in the amount of liquid helium remaining after a number of days.

The high stability and low vibration of the System ensures excellent data quality and low artefact (e.g. t1-noise) levels, even with demanding multidimensional NMR applications.

Specifications

Cryogen Reclamation System specifications
  • Boil-off performance depends on condition of magnet.
  • SCM requires liquid helium and liquid nitrogen during installation period.
  • Please contact us for magnets other than these listed.
  • It requires cooling water separately.
